இவர் கொங்கணரின் சீடர் என்றும் சித்தர்கள் காலம் எனப்படும் கி.பி 10-15 ஆம் நூற்றாண்டினர் என்றும் கூறுகின்றனர்.
"தாந் திமிதிமி தந்தக் கோனாரே
தீந் திமிதிமி திந்தக் கோனாரே
ஆனந்தக் கோனாரே - அருள்
ஆனந்தக் கோனாரே"
எனப் பாடுவோரும் கேட்போரும் குதித்தாடும் இந்தப் பாடல்கள் ஆசை என்னும் பசுவையும் சினம் என்னும் விஷப்பாம்பையும் அடக்கி விட்டால் முத்தி வாய்த்ததென்று எண்ணடா தாண்டவக்கோனே என்று கூறும் சிறப்புடை

Kalangi Nathar

Kālangi Nāthar was born in Kaśi (Benares). He attained the immortal state of swarūpa samādhi at the ago of 315, and then made China the center of his teaching activities. He belonged to the ancient tradition of Nava (nine) Nāth sadhus (holy ascetics), tracing their tradition to Lord Shiva. There are nine important shrines associated with this tradition, five of which are in the Himālaya Mountains: Amarnāth (where Shiva first taught Kriya Yoga to his Shakti partner, Parvati Devi), Kedarnāth, Badrināth (India), Kailāsanāth, (Tibet) and Paśupatināth (Nepal).

Pavala Kundru Siddhar Rock

The Pavala Kundru temple is dedicated to Lord Ardhanareeswara (androgynous form of the Lord as Half Shiva – Half Parvathi). It is here that Parvathi performed Tapas to regain the favour of her Lord Shiva. He then appeared to her and absorbed her into himself and thus the two became one. This is how Ardhanareeswara was born. There are not many temples dedicated solely to Ardhanareeswara and this is a rare and special temple though relatively unknown.
